you may check your lamp first. other than that i would say a faulty mains board.

this sounds like a dmd board problem. these are digital modules attached to the light engines usually. samsung, rca, hitachi, have shown similiar symptoms. some units have capacitors on the boards that can be replaced, but these are dual-layer pcb's that are tough to unsolder without proper soldering iron temperature and good small gauge solder-wick. or solder pump tool. the electolytic caps. are usually 1000uf / 10v, 330uf / 10v, or 470uf / 10v. alot of the time the capacitors will "vent" or swell-up on top which helps spot faulty component. we always increase voltage rating to 16v-25v for more reliable operation. always use 105 degrees high- temperature replacement caps.

it was bad bulb

This is the lamp going bad. For some reason, it doesn't spit out that lamp error, it just keeps refiring the lamp and it just cycles forever. When the lamp totally fails, you will get the lamp led lit. Replace the lamp to resolve.

Hi..if your lamp is on but no picture, then your lamp is good. Your problem is the DMD board (digital mirror display board) is bad. This is very common with Samsung DLP.

if your tv is on warranty take it back to the supplier.the problem with your tv is in the power supply there is a open regulator in that circuit along with the H .O. Transistor there is a black that feeds from the HOT to the flyback which also needs to check probably it is also open.good luck my friend
